Backstab is a conundrum, too. Thematically, it belongs to the rogue class like no other card, while game mechanics-wise it is barely seen in rogue decks. But i am happy to announce that with the appearance of Madame Rousseau, things could change in the future.

Backstab best suits investigators with a low combat and a high agility base.

Yes! Of course you got the same notion: i am speaking of 'my girl', Wendy. Backstab is one of the very few cards
that give her reliable access to additional damage. Fire Axe is expensive, Sneak Attack costs two actions and the bat probably breaks. This, and the fact that Pete players often import Backstab into their Dark Horse builds, makes Backstab feel like a red card in disguise.

A ridiculous combo possibility exists with Double or Nothing, if you manage to pump agility up that high. As a rule of thumb, +2 to +4 over the skill check difficulty on standard difficulty, so roundabout 10 to 12 agility.
Unlikely, one can pull this off alone. It is something you will definitely need another
investigator to help out with, since realistically you will be unable go accumulate
enough cards (Unexpected Courage/Manual Dexterity/Rise to the Occasion/Wendy's Amulet) for this ideal moment.
Or.... brooding over succeeding skill tests - it should be pretty smart to just exile Stroke of Luck as last card in a three-card-combo.

For the sake of clarity it should be noted that Backstab makes you test your agility skill
instead of your combat skill against the enemy's combat value. This implies that cards like Vicious Blow are not allowed to be commited to the skill test, as the rulebook states [RR V1.0, page 26, section 'skill test timing', ST.2]: "The investigator performing the skill test may commit any number of cards with an appropriate skill icon from his or her hand to this test. [..] Cards that lack an appropriate skill icon may not be committed to a skill test. [..]"

Combo with #Streetwise and you get a real killer combo.

What do you mean by "unconditional +2 damage"? Do you mean to say that regardless if the attack succeeds or fails, you still do the 2 damage?

No, if the attack fails, no damage is inflicted on the target. I meant that playing this card has no catch, it gives you a boost without a penalty (like discarding the card - Knife) or dependencies (.41 Derringer).
